A wealthy young Russian national and former MMA fighter was sentenced Friday to four years in a British prison for assaulting his girlfriend during a FaceTime call she was having with Barron Trump, an attack the president's son witnessed from Florida before dialing London emergency services to get her help.
Matvei Rumiantsev, 22, stood in Snaresbrook Crown Court in north-east London as Mr Justice Bennathan handed down the sentence: two years for assault occasioning actual bodily harm and two years for perverting the course of justice, the New York Post reported. The judge warned Rumiantsev he may be deported from the United Kingdom as a consequence of his convictions.
The case drew international attention not only for its violence but for the unlikely chain of events that led to Rumiantsev's arrest, a 999 call placed from thousands of miles away by the son of the sitting president of the United States.
The attack occurred in the early hours of January 18, 2025, inside a London flat in the Canary Wharf area. The woman, whose name has not been publicly released, was on a video call with Barron Trump when Rumiantsev allegedly flew into a jealous rage after seeing the incoming FaceTime notification on her phone, as the Daily Mail detailed.
What followed, prosecutors said, was an hour-long assault. The woman told officers she had been slapped, punched, kicked, and strangled. At 2:23 a.m. London time, Barron Trump, watching from Florida, called 999.
His words to the operator were direct:
"It's really an emergency, please. I got a call from her with a guy beating her up."
He gave the operator the woman's address. He told police he had met her on social media and described himself as "very close" to her. He also said the call had come roughly eight minutes earlier and expressed worry about what might have happened since. Police attended Rumiantsev's home in Poplar, east London, following two 999 calls from the woman and one from Barron.
As we previously covered when Barron Trump's emergency call first surfaced in the case, the young Trump acted quickly and cooperated fully with British authorities despite being an ocean away.
Justice Bennathan did not mince words about either man in the courtroom. He praised Barron Trump explicitly for his role in alerting police, Newsmax reported.
"Mr Trump properly and responsibly, despite being in the United States, made sure the emergency services here were called, and he told them what he had seen."
The woman herself credited Barron with saving her life. "He helped save my life," she said, adding: "That call was like a sign from God at that moment."
Barron, who turned 20 roughly a week before the sentencing, did not testify at trial. Fox News noted that Justice Bennathan instructed jurors to treat Barron's account cautiously because he was not cross-examined. The judge acknowledged Barron "could have been asked whether he actually saw the assault or whether he jumped to that conclusion based on her screams." But the jury convicted Rumiantsev on the assault charge regardless.
Two days after the attack, on January 20, 2025, Barron was photographed in Washington, D.C., at his father's inauguration, a detail that underscores just how compressed the timeline was between Barron Trump's intervention in the London assault and one of the most consequential political events of the year.
The sentencing judge painted a picture of a defendant who refused to take responsibility. Mr Justice Bennathan told Rumiantsev he was "a man given to jealousy" with "a temper," and described him as "totally unrepentant."
"Your lack of insight and empathy was apparent at trial. You continue to try to blame the complainant for everything that has happened."
The judge added: "That's a very long way from you facing up to the simple truth of what happened that night."
Rumiantsev himself had admitted during the proceedings that it was "hard for him not to be jealous" of Barron Trump's "persistent" contact with the woman during late 2024 and early 2025. He called the contact "inappropriate." But the jury evidently saw the jealousy as a motive for violence, not a justification.
After his arrest, Rumiantsev did not stop trying to influence the case. Prosecutor Serena Gates told the court that while in custody, Rumiantsev was overheard saying words to the effect of: "While you are sleeping in your warm bed, I'm in jail." He also tricked officers into allowing him to phone the woman from the police station. Eight days later, he called a friend named Arsen from prison and told him he had posted a letter for the friend to deliver to the woman.
He wrote to her from Belmarsh prison as well. AP News reported that Rumiantsev was convicted of perverting the course of justice specifically for sending the victim a letter from jail asking her to retract her allegations. The woman initially withdrew her statement but later retracted that withdrawal, telling authorities her original account was true.
That sequence, the phone calls, the letter, the pressure campaign from behind bars, is what earned Rumiantsev the second half of his sentence. The court treated it as a deliberate effort to derail justice.
Rumiantsev was not convicted on all counts. The jury found him not guilty of two counts of rape, one count of strangulation, and one count of assault by beating. His defense counsel, Sasha Wass KC, had described the woman's accounts of those alleged attacks as "untrue and fabricated."
The split verdict matters. The jury weighed the evidence charge by charge and drew a line. That is the system working as designed, convicting where the evidence supported conviction and acquitting where it did not. But the charges on which Rumiantsev was found guilty carried serious weight, and the judge made clear the sentence reflected both the violence and the sustained attempt to escape accountability afterward.
Rumiantsev is the second son of Sergey Rumyantsev, 53, the founder of One Price Coffee, a chain previously called One Bucks Coffee until Starbucks challenged the name in court. Companies House records list Sergey as a director of the company. He previously worked in sales for British American Tobacco and in international brand management and wholesale operations for Nike.
The family's roots are military. Sergey was born in Severomorsk, a closed Soviet naval town in the Murmansk Arctic region, and attended the Tver Suvorov Military School from age 14. Matvei's grandfather, Vitaly Rumyantsev, now 86, was a senior naval officer believed to hold the rank of captain.
Matvei attended Abbey College Cambridge, where school fees run roughly £80,000 a year. He appeared in a 2021 alumni reunion photo. The court heard he was a former MMA fighter. None of that wealth or pedigree spared him from a four-year sentence at Snaresbrook Crown Court.
Several questions linger. The woman's identity has not been disclosed publicly. The exact nature of her relationship with Barron Trump, she described herself as his friend and said she met him on social media, has not been elaborated on beyond those brief statements. Whether Rumiantsev will in fact be deported from the United Kingdom following his sentence remains to be seen; the judge flagged it as a possibility, not a certainty.
Trial judge Joel Bennathan had told the court before sentencing that Rumiantsev should expect a custodial sentence and that the probation service should provide reports. The sentence hearing took place on March 27 at Snaresbrook Crown Court, where Rumiantsev had been remanded in custody.
The contrast at the center of this case is hard to miss. A 22-year-old man from a privileged background, given every advantage money could buy, responded to jealousy with violence and then spent weeks trying to pressure his victim into silence. A young man an ocean away, the son of the president, heard a friend in danger and picked up the phone to call for help.
One tried to obstruct justice. The other set it in motion.
Character shows itself not in press statements or curated photos but in what people do when no one important is watching. At 2:23 in the morning, from thousands of miles away, Barron Trump made a call that may have saved a woman's life. The British judge who heard the case said as much from the bench. That's worth noting, not because of whose son he is, but because of what he did.
